' VENTI'LATING nE vrcE.

Specification of Letters Patent.

Patented Feb. v, 1922.

Application filed September 20, 1920. Serial No. 411,496.

To all whom it may concern:

Beit known that I, JAMES M. EDWARDS, a citizen of the United States, andresident of the city of New York, in the county and State of New York,have invented certain new and useful Improvements in VentilatingDevices, of which the following is a specification. j V

This invention relates to ventilating devices, and has for itsprimaryobject to provide inexpensive and effective means for regulatingand equalizing the temperature of a room; 7

The present invention in one embodiment thereof comprehends theprovision ofv means adapted for association with a suitable heat supplydevice'such as a gas or oil burner, or a radiator, the said device"being provided with a separate inlet passage for relatively cold airadjacent to the floor of the room, or from the exterior of the building,and also with means for thoroughly mixing the currents of cold and'warmair and disseminating the same into the room adjacent to the floorsurface.

In general the invention-contemplates the provision of a device for theabove purpose which may. be constructed. at relatively small cost, willoccupy a minimum of space, and in the successful operation of whichlittle or no additional expense will be involved. p r

With the above and other objects in view, the invention consists in theimproved temperature equalizing orregulating' device as Will behereinaftermore fully described, illustrated the accompanying drawings,and subsequently incorporated in the'subjoined claims.

In the drawlngs, wherein I have disclosed several desirable embodimentsof the 'invention, and in which similar reference characters designatecorresponding parts throughout the several views:

Figure 1 is a frontelevation partly in section, illustrating oneembodiment of my invention.

Figure 2 is a vertical transverse section showing the device arrangedvin operative position with respect to a radiator.

Figure'3 'is a section taken on the line 3- -3 of Figure 2, and,

Figure 4 is a view similar to Figure 2 illustrating a slightly modifiedform of the device.

Referring in detail to the drawings, 5

designates a casing preferably constructed of sheetmetal, and which maybe of any de sired size and dimensions. This casing is provided withfront and rear walls 6 and 7 respectively, and an intermediatevertically disposed partition wall 8 extending between the opposite sidewalls of the casing. The front wall 6 is provided in its lower portionwith the spaced openings 9 and 10 respec tively, while the rear wall 7terminates at its lower edge above and in spaced relation to thei bottomwall of the casing to provide an outlet opening 11 extending across theentire width of the casing; V relatively short vertically disposedtransverse partition wall 12extends between the front wall 6 and thepartition wall 8 of the casing, and is located between the openings 9and 10. The space above this transverse partition wall and between thefront wall6 and the wall 8 provides a mix ing chamber 13. I,

The partition wall 8 at the rear sideof the mixing chamber is providedwith an opening 14. A fan 15 is mounted between the wall 8 and the rearwall of the casing in axial alignment with this opening. This fan maybeoperated by any suitable means, and may either be mechanically driven,or operated automatically such cases Where a sufiiciently strong currentof heated or cold alr 1s available forthe purpose of driving said fan.

In the operation of the invention as above explained, a gas or oilburner may be arranged within or adjacent to the opening 9 in. thefrontwall of the casing, as indicated n Figure n th eated air i g a o ethe partition 12 will draw cold air through the opening 9 from the floorsurface of the room, and these hot and cold air currents are thoroughlymixed in the chamber 13 from which they. pass through the opening 14 inthe partition wall 8, and are driven downwardly by the fan 15 andthrough the outlet opening 11' at the rear side of the casing,

where the heated air is distributed over the surface of the floor. I

As is well known, in all apparatus now used for the heating of rooms orapartmentsthere is a relatively high temperature adj acent to theceiling of the room, while at the floor surface the temperature is manydegrees lower. Owing to the tendency of the heated air'to rise from theradiator or other heating apparatus, the occupant of the room oftensuffers actual discomfort owing to the fact that the air adjacent to thefloor surface is practically unheated. By means of my present inventionit will be seen that this deficiecncy in present heating apparatus isentirely overcome and the cold air adjacent to the floor is thoroughlymixed with the heated air current, and a column ofair of equalizedtemperature is then discharged over the floor surface.

As shown in Figure 2, the invention may be employed in connection withthe ordinary steam or hot water heating radiator which I have indicatedat 16, and in such case the opening 8 in the front wall of thecasing 5is arranged closely adjacent to the radiator columns, while the otheropening 9, constituting the cold air inlet, is exposed beyondthe end ofthe radiator. Of course it is manifest that the device might be made inelongated form, and hot air and cold air receiving openings of greatersize provided.

r In Figure 4 of the drawings I have indicated a slightly modifiedembodiment of the invention, wherein a pipe or conduit 17 is connectedto the front side of the casing 5 in line withthe opening 9. This pipereceives cold air exteriorly of the room, and is provided with asuitableregulating valve 18.

In the operation of this form of the device the air is not drawn fromthe floor surface through the mixing chamber, but exterior cold air ismixed with the current of heated air from the radiatoror other source ofheat. This embodiment of the invention is desirable where a very highdegree of heat is available, so that a constant supply of heated freshair instead of a partially vitiated air is constantly released into theroom. 7

From the foregoing description considered in connection with theaccompanying drawings, the construction, manner of operation andseveral-advantages of the invention will be fully understood. The deviceis exceedingly simple in. its construction, and can, therefore, emanufactured and sold at nominal cost. a Owing to the fact that nospecial heating apparatus is necessary, the operating cost will bepractically nil. It will be appreciated that a constantly equalizedtemperature of the air in a room or apartment may be maintained, and theair adjacent to the floor surface will always be substantially thesame 7temperature as the air at higher elevations.

It will be seen that there is no permanent connection of the device .tothe burner, radiator or other heating apparatus, so that it may bereadily moved from one room to another.

In the above description and the accompanying drawings, I have describedand illustrated several, desirable and practical embodiments of thedevice, but it is, nevertheless, to be understood that the same issusceptible of a great many modifications in the form, proportion andarrangement of its several parts, and I accordingly reserve theprivilege of adopting all such legitimate changes and modifications asmay be faily embodied within the spirit and scope of the invention asclaimed.

I claim:

1. A device of the character described comprising a casing having spacedopenings in one wall thereof, and a central vertical partition extendingbetween its side walls, a transverse partition located between theopenings and providing separate hot and cold air inlet passages,said'p'artition terminating below the upper end of said verticalpartition, the space above said transverse partition constituting amixing chamber for the hot and cold air currents, the rear wall of thecasing having an outlet opening at its lower end and a fan mountedwithin the easing to thoroughly mix. the hot and cold air currents anddirect the same through said outlet opening.

2. A device of the character; described 7 comprising a casing having hotand coldair inlet openings in its front wall andadjacent to its base,partition walls within said casing forming separate hot and. cold airpassages and a mixing chamber, one of said partition walls having anopening therein, the rear wall of the casing being provided with anoutlet opening at its lower end, and a mixing fan mounted adjacent tosaid opening in the partition wall to thoroughly mix the hot and coldair currents and dischargethe same through said outlet'opening.

3. portable ventilating device comprising a casing having means thereinproviding separate air inlet passages opening at one of their endsthrough one wall of the casing, said casing also having a mixing chamberwith which said passages communicate and an air outlet passagecommunicating with the mixing chamber and opening through another wallof the casing, the outlet passage having an area substantiallyequivalent to the combined areas of the. air inlet passages.

4:. A portable ventilating device comprising a substantially rectangularcasing having its interior divided by a plurality of partitions intoseparate hot and cold air inlet passages opening at one of their ends 7through one side wall of the casingat the lower endthereof, a mixingchamber with which the other ends of said passages. cornmunicate, and.an air outlet passage opening through the Opposite sidewall of saidcasing at its lower end and extending across substantially the entirewidth of the casing one ofisaid partitions having an opening thereinaffording communication between said outlet passage and the mixingchamber.
